Some parent could close its children members as well... :)

/*afx_msg for WM_CLOSE*/
void CParentDlg::OnClose()
{
  // CChildDlg CParentDlg::m_cChildAlert

  if (m_cChildAlert.GetSafeHwnd()) {
    m_cChildAlert.SendMessage(WM_COMMAND, IDCANCEL);
  }

  CDialog::OnClose();
}

This would be a massive abuse of first UI principles. Don't do it.

Look at this way: when you started a child modal dialog from running parent dialog, you don't have access to the parent dialog until the child ends the modal state. Not only you don't have a way to close all you need, you cannot access the parent. Dialogs can only stack one on top of the others. Even though this is legitimate behavior (in contrast to the one you want to have), this is a very bad style. Microsoft used to do 2-3 levels in all kind of Windows settings dialog, everyone made fun of it. It's always possible to re-design be behavior of just the one modal dialog, using, say tabs, enable/disable show/hide parts of the screen, using wizard style, etc.
